Short transcript:

Bernie Sanders: "In almost every instance in national polls and state polls, our margin over Trump is wider than Secretary Clinton's. With the victory in Wisconsin tonight we have now won seven out of eight of the last caucuses and primaries. And we have won almost all of them with overwhelming landslide numbers."

"In a time in contemporary politics, when every candidate has super PACs, we have said no to the billionaires who fund those super PACs. And what we have done is, in an unprecedented manner in American history, we have up to this point in the campaign received over 6 million individual campaign contributions." 

"We have decided that we do not represent the billionaire class, we do not represent Wall Street and we do not want their money."
